No MacWorld SF Keynote Broadcast?
According to "an Apple note" forwarded to the site:
Apple will not be making satellite coordinates available. Although the keynote WILL be available on our web site - it will NOT be available until sometime AFTER the keynote is over. They do NOT have a time determined, so it may not be immediately after the keynote is over.
In recent years, Apple has provided both webcast and satellite broadcasts of MWSF Keynote speeches. No official announcements have been made, but, with only five days to go, the window is closing.
